Default 97-98 LS1 Fuel rail hook up

I searched, but could not find the answer. I am trying to use a return style fuel rail, (97-98 ls1) but I do not know which port is feed and which is return. Could someone help me out? Thanks

Feed is usually 3/8 and return is usually 5/16. Edit: I just looked at a pic of those rails and i cant see a difference in size. Does one end T into the metal lines and one comes out of the regulator?

http://www.hotrodlane.cc/JEEP/jeep2.htm take a look ...looks like the line coming out of the back of the regulator is the return.

You can see the braided feed line entering the driver's side rail.
I've altered the return line so that it connects to a Corvette reg at the rear of the car.

In this picture, the braided line in the rear is the return.

Don't you have to do something with the fpr on the rail? it will still control the fuel pressure.

The former regulator in the rail has been gutted.
